Claims (4)
1. Способ очистки 5Н-дибенз[b,f]азепина, отличающийся тем, что на первом этапе выпаривают 5Н-дибенз[b,f]азепин при пониженном давлении из реакционной смеси, полученной путем каталитического дегидрирования 10,11-дигидро-5Н-дибенз[b,f]азепина, и выделяют его в виде твердого вещества, на втором этапе продукт суспендируют в ароматическом углеводороде и затем выделяют чистый 5Н-дибенз[b,f]азепин.
2. Способ по п. 1, отличающийся тем, что первый этап проводят при температуре между 120 - 260oС.
3. Способ по п. 1, отличающийся тем, что первый этап проводят при давлении между 10 - 100 мбар.
4. Способ по п. 1, отличающийся тем, что отделенный продукт суспендируют в толуоле.
